Microsoft's Malvertising Lawsuits Try to Find Hackers

Microsoft announced yesterday that it filed five (5) lawsuits (shown below) in Washington State court to try and learn the identities of people who used the company's adManager service to distribute malicious online advertising, better known as 'malvertising.'

According to Tim Cranton, Microsoft's Associate General Counsel, the malvertising operated under the business names of "Soft Solutions," "Direct Ad," "qiweroqw.com," "ITmeter INC." and "ote2008.info."

Cranton said that the malvertisements placed were used "to distribute malicious software or present deceptive websites that peddled scareware to unsuspecting Internet users."

Microsoft is informed and believes...that Defendants have been--and are currently involved in--writing and distributing computer trojans targeted [sic] the computers and computer systems of businesses and consumers using Microsoft software, among others

Defendants operate a number of scareware websites...designed to resemble the look and feel of Microsoft's Windows Vista operating system.

* * *

Defendants misrepresentations include a list of purportedly detected "dangerous spyware" with "critical severity"...[and] the website generates a "Microsoft Security Warning" pop-up message that deceptively uses Microsoft's Marks to suggest that Microsoft is associated with the warning message."

But should Apple aficionados and Open Source users be concerned?

Although sophisticated malware can still affect Unix and Mac OS, neither OS appears to have been targeted by these particular malvertisers.

Cranton, Microsoft's lawyer explained Microsoft's position on why combating "illegal activity that undermines people's trust in the Internet and online services" is so important to their business: "It pays for free online services like Windows Live, Facebook, Yahoo and MSN."
